I'm using a shackle too, but I'm not 100% sure,if I will get out of it. It is great riding without having to worry getting out of the depower, specially when your overpowered.
Maybe you should use both.
The Flysurfer Quick Realease is great and works

the flysurfer chickenloop looks to me, like it's 100% working.

told, that in the beginning it may happen that you hook into the release-strap and open the system by accident.
but you can put it together it without any problems on the water.

I think the tylaska costs too much. Have you seen how the americans charge so much more for everything. I mean, compare kite prices from U.S. stores to stores in Europe, Australia, New Zealand. Sometimes there are 400 US dollar differences. I understand it is a strong snap shackle, but it is just too much. NSI in general is too expensive, the bar costs 190 us. Do you guys also think they charge too much?

Well, compared to the prices in some European coutries, others are charging a lot. In general the kites are very expensive.
But the shackle I use costs abouit 50 USD as well. And this is ok if it is lasting material and a system that works.

Please help an overburdened Yank consumer by telling me where I can buy kitegear online in Europe (or wherever) at better prices than I find here? I would be StOkED but you know what I mean! If you could hook me up with links to $$$ saving English version online kiteshops, I'd be really, really happy!

Dude,http://www.kite.net.au is really cheap for peter lynn stuff, and I think naish too. The prices on his site, you take 10% off because of the australian tax. He ships for free when you buy anything above 100 aud. I live in Mexico, no kiteshops, and he sent the kite to mexico, great service, nice guy. http://www.anabatic.co.nz is pretty good, http://www.kitepower.com.au says he'll equal any price by a competitor. Traig trumbo at http://www.monkeyair.com in Malibu, great prices for arcs and underground boards. Check them out, contact them, decide for yourself.
